About TextToolkit

TextToolkit is a collection of free, browser-based text utilities built by NS Ascertain. Convert case, compare documents, encode data, and more — without creating an account or uploading your content to a server.

Every tool runs locally in your browser. Your text stays on your device, which makes TextToolkit suitable for drafts, code snippets, and sensitive content you do not want to send over the network.

Our other tools

We also build FileToolkit, a free suite of file utilities with the same privacy-first approach. Visit nsascertain.com to learn more about our work.
